CXCL1 is closely associated with tumorigenesis in gastric cancer, as CXCL1 expression is positively correlated with advanced TNM stage, i.e., T invasion stage, lymph node metastasis, as well as tumor size [97,98,101,107,109,112,115]. Here, CXCL1 is linked to metastatic malignant neoplasm in the lymph nodes.
